Ctenodon viscidulus (Michx.) D.B.O.S. Cardoso & A. Delgado . [ Fabaceae ] Sticky Jointvetch

This report represents the second known collection of this historic taxon ( SH / G5 ) from Alabama, the first since Dr. Charles Mohr collected it from Dauphin Island (Mobile County) in July 1878. Uncommon in a bare sandy opening of a grassy lawn-like expanse of an old Spanish cemetery, plants were localized to a small area. This native taxon is more commonly found in neighboring Escambia County , Florida and much of central Florida. However , outside of this area, C. viscidulus is only sporadic from coastal Georgia counties westward to Texas. The rarity of this somewhat hard-to-detect species may be due to it being an ephemeral, short-lived perennial in disturbed or borderline suitable habitat.
